Verbal interaction pattern analysis in clinical psychology

Recent developments in pattern analysis research have made this methodology suitable for the study of the processes that are set in motion in psychological interventions. Outcome research, based on the comparison between clinical results from treatment and control groups, has leveraged our empirical knowledge about the efficacy of psychological interventions. However, these methods of research are not precise enough for the analysis of these processes. On the contrary, pattern analysis could be a powerful tool to study moment-to-moment interactions typical of psychological interventions. This is methodology is relevant because clinical psychology is experiencing a paradigm shift from a protocol for syndrome perspective to a principle-based and person-centered intervention. This evidence-based, theory-grounded, and process-oriented paradigm of clinical intervention needs new research methods to thrive (i.e., pattern analysis). The analysis of the therapeutic relationship built into the verbal interaction between the clinician and the client is one of the cornerstones of this new era of research. So, the purpose of this article is three-fold: (1) to discuss the role of the verbal interaction pattern analysis in the clinical context to the development of the principle-based clinical psychology, (2) to analyze the patterns of verbal interaction in a clinical case, and (3) to compare the results using two different methods. To reach these purposes, using the observational methodology, we have coded the verbal interaction of 16 clinical sessions with a person diagnosed with a borderline personality disorder. We have analyzed the data using sequential analysis (GSEQ) and pattern recognition algorithms (i.e., T-Pattern detection). We have been able to detect typical patterns during different phases of psychological intervention (i.e., evaluation, explanation, treatment, and consolidation). Finally, the conceptual, methodological, and empirical implications of this study will be discussed within the realms of pattern analysis research and principle-based clinical psychology.

The Impact of Therapists' Responses to Resistance to Change: A Sequential Analysis of Therapist Client Interactions in Motivational Interviewing

AIMS

The study aims to examine how therapists trained in motivational interviewing (MI) respond to resistance and whether this has an impact on subsequent client speech.

METHODS

Fifty recorded Motivational Enhancement Therapy sessions were examined using a sequential behavioural coding method for speech. Client counter-change talk formed the baseline for coding and categorizing subsequent therapist speech and the following client speech. Transitional analysis identified the probable occurrence of specific therapist and client utterances at each stage.

RESULTS

Following client expressed resistance or counter-change talk, MI consistent therapist utterances were most commonly observed. A moderate to strong predictive relationship was found between MI-consistent therapist speech and subsequent client change talk. A moderate predictive relationship was found between therapist MI-consistent behaviours and client ambivalence. A moderate to strong predictive relationship was found between MI-inconsistent therapist speech and subsequent client counter-change talk and a weak negative predictive relationship was found between MI-inconsistent therapist speech and client expressed ambivalence.

CONCLUSIONS

In the face of initial expressed resistance to change, MI-consistent therapist speech appears to increase subsequent client utterances regarding intentions to change drinking behaviour.
